The purpose or this study was to develop a simple mouth-opening training device to prevent muscle contracture after arthroscopic surgery of the TMJ. We performed a compression strength test of a newly developed polyethylene hydraulic pump, which is a built-in pump for the mouth-opening training device, until water leakage. The compression test was performed using an Autograph G10KN1 (Shimadzu) at a compression rate of 5, 10, and 20 mm/min, and the compression strengths were 150.0, 397.0, and 388.1 N, respectively. Considering occlusion force in humans, this polyethylene hydraulic pump appeared to have adequate strength. Next, to determine the shape of the mouth-opening training device, trial devices were produced.Trial product type I was obtained by cutting aluminum cylinders using a lathe and modified. A metal mold was produced, and trial product type II was obtained. For clinical application, trial product type II with a polyethylene hydraulic pump was used for mouth-opening training after arthroscopic surgery of the TMJ in 2 patients. The feeling during use was investigated and compared between the new device and conventional air-delivery type rubber mouth-opening training device. The results were better for the new device.

本研究的目的是开发一种简单的张口训练装置，以防止关节镜手术后颞下颌关节肌肉挛缩。我们对新开发的聚乙烯液压泵进行了抗压强度测试，该泵是张口训练装置的内置泵，直到漏水。使用Autograph G10 KN 1（岛津）以5、10和20 mm/min的压缩速率进行压缩试验，压缩强度分别为150.0、397.0和388.1 N。考虑到人体的闭合力，该聚乙烯液压泵似乎具有足够的强度。接着，为了确定张口训练器的形状，制作了试验装置，使用车床对铝圆筒进行切削加工，得到了试验品I型，并进行了改良。制作金属模具，得到试验品II型。对于临床应用，在2例患者的TMJ关节镜手术后，使用II型试验产品（带聚乙烯液压泵）进行张口训练。并与传统的送气式橡胶张口训练器进行了使用感觉的对比研究。新器械的结果更好。
